UINavigationItem：添加一個按鈕

enter image description here UINavigationItem：添加一個按鈕

如何在navigationItem中添加新按鈕？假設我需要將它添加到右鍵附近。

用於左右的代碼。

self.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:_cancelButton]; 
self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:_shareButton];

如何添加一個按鈕？

@Jyotishree謝謝...讓我試試這種方式。 – iPhoneProcessor 2013-05-08 12:37:10

將按鈕添加到UIView，然後將該視圖添加爲正確的bar buttonitem。 – jamil 2013-05-08 13:04:53

有不同的方法來添加上的Simplist方式navigationcontroller.one的右側多於一個按鈕下面

UIView *buttonView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 100, 44)]; 

UIButton *exampleButton1 = [UIButton buttonWithType:UIButtonTypeCustom]; 
exampleButton1.frame = CGRectMake(0, 2, 30, 40); 
[exampleButton1 addTarget:self action:@selector(FirstMethod) forControlEvents:UIControlEventTouchUpInside]; 
[exampleButton1 setImage:[UIImage imageNamed:@"image1.png"] forState:UIControlStateNormal]; 
[buttonView addSubview:exampleButton1]; 


UIButton *exampleButton2 = [UIButton buttonWithType:UIButtonTypeCustom]; 
exampleButton2.frame = CGRectMake(70, 2, 30, 40); 
[exampleButton2 addTarget:self action:@selector(Second method) forControlEvents:UIControlEventTouchUpInside]; 
[exampleButton2 setImage:[UIImage imageNamed:@"image2.png"] forState:UIControlStateNormal]; 

[buttonView addSubview:exampleButton2]; 

self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:buttonView];

給出希望這將是周到，謝謝

試試這個。它爲我工作。

UIBarButtonItem *flex = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFixedSpace target:nil action:nil]; 
    flex.width = 20; 
    UIButton *btn = [UIButton buttonWithType:UIButtonTypeCustom]; 
    [btn setFrame:CGRectMake(0, 0, 40, 30)]; 
    [btn setImage:[UIImage imageNamed:@"mac-gray.png"] forState:UIControlStateNormal]; 

    UIBarButtonItem *bar1 = [[UIBarButtonItem alloc]initWithCustomView:btn]; 

    UIButton *btn2 = [UIButton buttonWithType:UIButtonTypeCustom]; 
    [btn2 setFrame:CGRectMake(0, 0, 40, 30)]; 
    [btn2 setImage:[UIImage imageNamed:@"mac-gray.png"] forState:UIControlStateNormal]; 

    UIBarButtonItem *bar2 = [[UIBarButtonItem alloc]initWithCustomView:btn2]; 

    self.navigationItem.rightBarButtonItems = [NSArray arrayWithObjects:bar1,flex,bar2, nil];

不適合我...因爲我使用了單獨的文本... – iPhoneProcessor 2013-05-08 12:19:51

@iPhoneProcessor這對你有幫助嗎？ – NightFury 2013-05-08 12:38:15

您可以添加更多按鈕

self.navigationItem.leftBarButtonItems = [NSArray arrayWithObjects:uibarbuttonInstance1, uibarbuttonInstance2, nil];

同爲右按鈕

self.navigationItem.rightBarButtonItems = [NSArray arrayWithObjects:uibarbuttonInstance1, uibarbuttonInstance2, nil];

不工作....請看我的代碼片段http：// pastebin。 com/iKt3dTGT – iPhoneProcessor 2013-05-08 12:34:20

中鍵

UIButton *btnShow = [[UIButton alloc]initWithFrame:CGRectMake(0, 0, 34, 34)]; 
    btnShow.backgroundColor = [UIColor colorWithWhite:0.411 alpha:1.000]; 
    [btnShow setImage:[UIImage imageNamed:@"btn_back.png"] forState:UIControlStateNormal]; 
    [btnShow setImage:[UIImage imageNamed:@"btn_back.png"] forState:UIControlStateHighlighted]; 
    self.navigationItem.titleView = btnShow;

右鍵欄按鈕

UIButton *tempButton1 = [UIButton buttonWithType:UIButtonTypeCustom]; 
    [tempButton1 setFrame:CGRectMake(0, 0, 34, 34)]; 
    tempButton1.tag = 0; 
    [tempButton1 addTarget:self action:@selector(btnBackClicked:) forControlEvents:UIControlEventTouchUpInside]; 

    [tempButton1 setImage:[UIImage imageNamed:@"btn_back.png"] forState:UIControlStateNormal]; 
    [tempButton1 setImage:[UIImage imageNamed:@"btn_back.png"] forState:UIControlStateHighlighted]; 
    [self.navigationItem setRightBarButtonItem:[[UIBarButtonItem alloc] initWithCustomView:tempButton1]];

左欄按鈕

UIButton *tempButton = [UIButton buttonWithType:UIButtonTypeCustom]; 
[tempButton setFrame:CGRectMake(0, 0, 34, 34)]; 
[tempButton addTarget:self action:@selector(btnBackClicked:) forControlEvents:UIControlEventTouchUpInside]; 
[tempButton setImage:[UIImage imageNamed:@"btn_back.png"] forState:UIControlStateNormal]; 
[tempButton setImage:[UIImage imageNamed:@"btn_back.png"] forState:UIControlStateHighlighted]; 
[self.navigationItem setLeftBarButtonItem:[[UIBarButtonItem alloc] initWithCustomView:tempButton]

不適用於我...用於titleView的文本... :( – iPhoneProcessor 2013-05-08 13:16:48

在TitleView中，您已經放置了文本或什麼？好吧...如果是這樣......您需要文本和按鈕或者文本本身作爲按鈕 – 2013-05-08 13:19:09
